Preheat Oven: Preheat your oven to 350°F (175°C) and grease a 4x8 inch loaf pan.
Mix Ingredients: In a mixing bowl, mash the ripe bananas with a fork until smooth. Stir the melted butter into the mashed bananas.
Combine: Mix in baking soda and salt. Add sugar, beaten egg, and vanilla extract, and mix until combined. Finally, stir in the flour until just incorporated. Do not overmix.
Add Chocolate Chips: Gently fold in the chocolate chips.
Bake: Pour the batter into the greased loaf pan and bake for 60-65 minutes or until a toothpick inserted into the center comes out clean.
Cool and Serve: Let the bread cool in the pan for 10 minutes, then transfer to a wire rack to cool completely before slicing.
